Yes I tried it too - I think it was only launched a few weeks ago so it is still very much a work in progress - the idea is a good one and the UI is very clean from what I have seen so far.
I agree with Zach. Having spent many months optimising keyword selection, ad copy and landing page selection to get high keyword quality and CTR I would like to know more about what principles adspike adopts to improve the adwords campaigns. Also does adspike work for search, or display, or search and display campaigns.
